My situation's different but I've observed that SOME (certainly not all) try to do a geographical cure & they could wind up in a suite in the Ritz & not be happy. Others may be newly retired & suddenly they're together 24/7 which is a totally new experience & not always a pleasant one. You've seen them in restaurants. They're the couple that have not said a word to each other throughout the whole meal.
It helps to have realistic expectations & there's no harm in finding that this area isn't the place for you but somewhere else may just be perfect. I asked on this board before I came what I should bring with me. Most of the men said "Lose the stuff." The women were smarter & I'm glad I followed their advice. It would have been too costly to move furniture but I sure brought towels, sheets & kitchen stuff & paintings I valued.
For anyone who isn't used to moving around different cultures it really is best to rent for a while & for those who do leave I hope they find their sweet spot.
